public static void main(String[] args) {
Scanner inputSomething = new Scanner(System.in); // Creates an object of type 'Scanner' named 'inputSomething'

// Declaring variable 'someVar' of type integer and waits for user's input

Answer 2

can you explain what is .nextlnt ();

Answer 3

It's expecting an integer for input.
'nextLine()' expecting a String value.
The rest are obvious: 'nextByte()', 'nextShort()' and so on.
